Strange, for me it compiles (with a bunch of warnings, which I have
fixed locally), and links just fine.  However, I always use -std=c++11,
which -std= flag are you using, if any?

That said, I am planning on importing a new drop of libc++ soon, but I
would rather see this fixed sooner than later.  So I will cherry-pick
a few fixes tonight.

Meanwhile, here are the local diffs I have for making atf build.

PS: As far as I can see, atf doesn't build at all with clang and
libstdc++, because there are many warnings caused by -Wsystem-headers...
Is there any incentive to fix these?
